There are a total of 14 arson cases in west Birmingham, where Thornton, 27, is a patrol officer. He is charged with setting fire May 21 to a home at 1708 29th Street Ensley.

Thornton is in the Jefferson County jail on $150,000 bond.

Birmingham Police Chief A.C. Roper issued a statement about the charge shortly after the announcement:

"We are disappointed the evidence has [led] us to the wretched task of arresting someone we trusted to protect the lives and property of our citizens. This type of conduct makes it difficult for our professional and sworn personnel that provide tremendous services to our citizens. We will continue to conduct a thorough and deliberate investigation to bring the remaining investigations to a conclusion."
